Alright, so now the JASS download should work as intended on the 
SAD homepage (www.arch.kth.se/sad, under "projects"->"software").

A few notes:
The download is still a zip which you have to extract, it is 
just a zipped jass.jar. Not to bore you with details, but it 
appears that Internet explorer (at least) "helpfully" renames 
any .jar to .zip if you download it, so now I created a proper 
zip containing the .jar file. (jazz.jar_zip.zip is the full name 
of the file).


On a related note, concerning the discussion on j-graphs:

Isn't the j-graph (justified graph) the one with a (or several) 
root node(s) and the other nodes arranged in levels per step 
depth, usually upwards? There are two problems with these 
graphs, as far as I know. 

One is calculating the measures. Depthmap at home seem to work 
fine for this, as suggested.

The other is translating the original graph 
(called 'permeability graph' in SLoS, I think) into the 
justified graph, which is far from an easy thing to do for more 
complex systems. Try an entire public library. It's also a 
fairly tricky thing to code, I've been told by many-a 
programmers, counter to what one would think. At least if you 
want no connections to intersect one another, and especially if 
you want them to not do so on the same depth (horizontal 
connections in the j-graph).

The primary function of JASS is to help with the second one, and 
give you a J-graph which you can modify yourself by moving the 
nodes each on their own depth (once converted to a j-graph the 
nodes are locked on the vertical plane, but can be moved 
horizontally) so you can more easily unclutter the j-graph. As 
far as I can remember now, this was prioritised as we worked 
with the software, which is still really far from "finnished", 
over calculating measures, even if some measures (at least RA 
and RRA) can be calculated, and (I think) exported to a table 
(at least shown as a table).

Hopes this helps to clarify further if you had any remaining 
questions.
